I just built a Video Editing & VFX system on a TRX40 platform with 256GB RAM (32gb x 8, 3200MHz) – and it looks like windows is only picking up half of it. This is my 2nd build and is very easy to adjust and access. Temps are good, BIOS is up to date, and I just checked all DIMMs & Modules as well as the pins on the processor - Everything is looking sharp on the hardware front (brand new).
• Bios, Task Manager, & CPUz/HWInfo show all 8 sticks at speed, and whether I run the XMP profile for the 3200 speed or set them to default, I get the same result – with my task manager showing 256GB installed but only 128GB Hardware Reserved and available. When Running 4 Dimms it shows 128 with 128 available, and seems fine.
• I checked my boot option in msconfig and it is not limiting my RAM
• I checked BIOS for iGPU settings, but there is no onboard graphics card to mess with and I cannot find a spot to disable anything in BIOS.
• This motherboard supports Quad Channel memory, up to 32GB x 8 @3200, the matched set of G.Skill Ram I have installed is on the supported QVL list from the motherboard manufacturer’s Website (Asrock).
I have searched online & made several BIOS adjustments to no avail, and this limited ram issues has me quite perplexed. I am thinking this might be a simple fix for someone smarter than me, but not sure if it can be diagnosed from the info provided.
I am not sure if I need to disable something in BIOS, but all of my components should play together nicely:
Noctua Air Cooler (temps: 39c-80c)
Asrock Trx40 Creator (BIOS Verison 1.7)
GSkill 256GB Trident NEO - (8x32GB, 3200)
EVGA RTX 2080 Super (Nvidia Studio Driver)
EVGA 1300W Supernova Gold + PSU
…any help would be appreciated!!
